The Labour Saving One-Shot Mounting System
Redback “One-Shot” speaker units install in seconds providing substantial labour cost savings for the professional installer compared to traditional mounting methods. They simply snap fit to the outer mounting ring by means of the integral pressure clips. The snap clip material is formulated to retain long service life strength and spring action, ensuring a firm vibration free fit.

Speaker cable entry can be either from the rear, or via surface mounted conduit (four 19mm conduit knockouts are provided). The neutral white RAL colour provides an architecturally unobtrusive finish to virtually any installation. The transformer is fitted with a 4 way wire protect screw terminal block. This is suitable for loop in, loop out cabling.
